Let us start with 70% who lost one eye  
Consider 80% lost one ear. 
This means 20% did not lose one ear.  
Suppose this 20% all lost one eye as well.  
This means 70% - 20% = 50% lose one eye and one leg  

Consider 75% lost arm next.  
This means 25% did not lose arm.  
Suppose this 25% all lose one eye and one ear.  
This means 50% - 25% = 25% lose ear, one eye and one arm  

Consider 85% lost a leg  
This means 15% did not lose leg.  
Suppose this 15% all lose ear, one eye and one arm.  
This means 25% - 15% = 10% lost all 4 limbs.  
Now, it is given that x% lost all four limbs. So, x=10

20% of combatants hasn't lost one ear
25% of combatants hasn't lost one arm
15% of combatants hasn't lost one leg
Who has lost atleat one limb = 30+20+25+15
                                                    = 90%
Who has lost all four limbs = 100-90=10%
